IMPROVEMENT iN GANGANDSUBSCIL FLOWS.

Specification foriningpart of Letters Patent No. ll3,390, datedy April 4, 187i.

Toall whom it may concer/n:

Be it known that I, J. L. BOND, of Marshalltown, in the county of Marshall, and in the that the following is a full, clear,.and exact `description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon', making a part of this specification.

The nature of my` invention consists in the construction and arrangement of a combined single, gang, and subsoil plow with grain and 4 fornnlanter attachment, which is intended as Aan improvement upon a similar machine for which I have already applied for Letters Patent.

In order to enable others skilled in the art to which my invention a ppertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in whichv Figure l is a plan view, and Fig. 2 a side elevation', of my present machine.

A represents j the plow beam, and B B the l handles, of any ordinary plow.

C represents an upright bar attached to the mold-board D and landside E, the handles B B beingl at their lower ends, by any suitable means, also connected with said mold board and landside. The barGpasses between guides en metal plate G, which is fastened to the landside of the plow-beam in the following manner: The rear end of the plate Gis piv -oted to the plow beam and secured 4by two clamps, a a,the clamp a passing in an oblique direction around the beam and the plate at the pointwhere the barC passes between the guides on the plate, so that this clamp, at the same time as it holds the plate G, also firmly secures the barG at any desired height. The clamp a' passes around the beam and plate at the front end of the plate. The front end ofthe plate Gis made narrower than thisclamp, so that the plate can be raised or lowered at pleasure to regulate the depth at which the plow is .to work.

On the mold-board side of the beam A, a

suitable distance from and parallel with it, is another beam, A', the two beams being eon nected at their front ends by means of acrossbar, H, to which the clevis I is fastened. rIhe rea-r end of the beam A is held securely by means of a' bent metallic brace, J, the ends of which pass under or inside ofthe clamps a a', while the center bears against the inner side of the hea-m A' and is held by a clamp, b, all as shown in Figl. To the beam A' is attached another plow, formed et' the mold board D',

landside E', and upright bar C', thus forming, in the Samemanner as described in my former application, a gangplow and a snbsoil -plow. The upright bar passes between guides on a plate, G', the rear end of which is piyoted to the beam A' and held by the clamp I; in the Vsame manner as the clamp a holds the plate G- to the beam A, as above mentioned. The front end of the plate G' is slotted, as shown in Fig.

2, and a screw-bolt with thumb-nut dfastens it to the beam A'. By this means this plate may also be raised and lowered at will to reg" ulate the depth at which its plow is to work.

On top and across the beams A A', in suitable staples or boxes, are placed two rods, K K', which are' adjustable in so far that they may be drawn out or pushed in at will to regulate the distance at which the gage-'wheel M is to work from the beam A'. To the front one, K, of these rods'is .hinged orpivoted the front end of the gage-wheel frame L. The rear end of this frame terminates in a bar, c, which passes through a loop, j", formed on the end of the rear rod, K', so that the said frame may be raised or lowered at will to regulate the depth at which the gagewhecl M is to operate. Within the frame L the said wheel M is placed, and to the outer 'side of the frame is attached the corn and seed drillatfachment N, said attachment being constructed and fastened in substantially the same manner as described in my former application aboye referred to. The operation of this machine is also the saine as in my former case.

Having thus fully described my inventim, what I claim as new, and desire to secure by Letters Patent, isa

2 l A M3390 1. The arrengementof the bcamsAA', crossbar H, bent brace J, plates G G', clamps a a and b, bolt and nut d, and the plow-bars C C', all substantially as shown and described, and for the purposes herein set forth.. v

2. The arrangement, with the frame-beams A A', 0f the adjustable rods K K, frame L, bar e, loopf, seed-drill box N, and gage-wheel M, all constructed and operating smbstantiallyr as set forth.
